INVEN OR. MELVIN FINEMAN United States Patent 3,474,796 HAIR ROLLERS Melvin Fineman, 7835 Crespi Blvd., Miami Beach, Fla. 33141 Filed Mar. 28, 1967, Ser. No. 626,513 Int. Cl. A45d 2/00 US. 'Cl. 13238 Claims ABSTRACT OF THE DISCLOSURE SPECIFICATION This invention relates in general to apparatus for coifiures and more particularly to hair waving devices, commonly called rollers.

Prior hair waving rollers are commonly made from metal or dense plastic materials and when the hair is properly wound on rollers of this character, the drying of moisture or lotions is exceedingly slow because of the limited circulation of air through the hair, which is tightly wound on the rollers. Furthermore, the

present hair roller is cylindrical in shape having a predetermined length which limits the degree of span of the wave responsive to each roller.

The present invention overcomes the above disadvantages and limitations by the provision of three types of rollers made from a particular compacted crystalline material having a high moisture absorption rate, which greatly decreases the time required for the drying of moisture or lotions applied to the hair and is a principal object of the invention.

A further object of the invention is the provision of an auxiliary extension roller for extending the effective length of a single roller to accomplish a greater span of wave in the hair.

A further object of the invention is the provision of a segmental hollow roller having toroidal shape for rapidly producing by absorption an arcuate form of wave in the hair.

These and other objects and advantages of the invention are described and shown in the following specification and drawing, in which:

FIG. 1 is a perspective view of a ceramic hair roller.

FIG. 2 is a cross sectional view of the roller shown in FIG. 1, illustrating hair wound thereon.

FIG. 3 is a perspective view of an alternate form of roller for extending the effective length of the roller shown in FIG. 1.

FIG. 4 is a cross sectional side view taken through section line 44, FIG. 3.

FIG. 5 is a perspective view of a hollow sector of a roller having toroidal shape.

FIG. 6 is a cross sectional view taken through section line 6-6, FIG. 5.

Referring to FIG. 1, a basic roller 1 is a hollow elongated cylinder having dimensions in the order of an axial length of three inches, an outside diameter of one and one-quarter inches, and an inside diameter of seveneighths of an inch.

The principal feature of the roller shown in FIG. 1 resides in its composition, which may be made from cer- 3,474,796 Patented Oct. 28, 1969 tain natural occurring pottery earth, or diatomaceous earth, or mixtures of natural occurring minerals which include silicates, aluminum and/or calcium elements, or refined crystalline calcium sulfate, which has been screened to predetermined diameters.

The aforesaid materials are granulated and screened to a predetermined fineness in the order of screen size and suflicient moisture added to provide an adherence of the granules for molding.

The cylinder is molded from the moistened material by the use of well-known molds and methods utilizing high pressures, thus forming a self-supporting cylinder which is then oven baked at a predetermined temperature until a desired high hygroscopic degree of porosity and rigidity is obtained by controlled fusion.

The cylinder thus molded is porous in nature and has sufiicient interconnected microvoids therethrough to absorb and retain a quantity of liquid by capillary action when in contact with wet material, such as hair.

FIG. 2 illustrates hair 2 wound around the roller 1 while in damp or wet condition as a result of treatment by water or volatile lotion. Since a portion of the hair wound on the roller is in intimate contact with the outside surface of the cylinder, the moisture or lotion is quickly absorbed and removed from the hair in considerably less time than if wound on non-absorptive metal rollers or plastic rollers and subject to evaporation only.

The drying of the hair is also accelerated by the evaporation of moisture from the inside surface of the roller due to the free passage of air therethrough.

FIGS. 3 and 4 illustrate an extension roller 3 having a cylindrical collar 4 of smaller diameter extending a predetermined distance from one end thereof forming a shoulder 5. This extension may be used in connection with the roller shown in FIG. 1 where a continuous hair wave of greater width is desired.

Referring to FIGS. 5 and 6, a curved hollow roller 6, generally in the form of a sector of a hollow toroid and having a wall thickness comparable to that shown in FIG. 1, is molded from one of the aforesaid absorptive materials and curved to form an irregular shaped wave, when desired.

In operation, the damp or wet hair is closely wound about the outer periphery of the roller and held close to the scale by well known clips or pins. Where a wave of greater width is required, the second form or extension roller is telescoped to the first form to provide a greater length and used in the same manner.

The third form of roller, having the shape of a segment of a toroid, is used in the same manner as above when a hair wave or arcuate shape is desired.

It is understood that certain modifications in the above construction, utilizing the features described, are intended to come within the scope of the appended claims.

Having described my invention, I claim:

1. A hair waving roller comprising a hollow elongated cylinder of predetermined length and diameter and having a substantially coaxial bore therethrough of predetermined diameter,

the entire said cylinder die-formed from granular inorganic crystalline material and fired to predetermined porosity and rigidity whereby a portion of the moisture in hair wound thereon will be absorbed thereby.

2. The construction recited in claim 1 wherein said material comprises compressed diatomaceous earth.

3. The construction recited in claim 1 wherein the said material comprises compressed substantially uniform granulated calcium sulfate of predetermined size.

4. A hair waving cylinder comprising a hollow cylinder having a length to diameter ratio of substantially 3 4 3 to 1 and a ratio of internal to outside diameter of submined porosity and rigidity whereby a portion of the 'stantially 10 to 7, moisture in hair wound thereon will be absorbed the entire said cylinder die-formed from granular inthereby.
